Co sleeper beds for infants. Which ones are best?

Ki

So we’re expecting twins and I’ve been trying to figure out the most comfortable safe way to allow to babies to be close to hubby and I so I can exclusively nurse. We plan to get a King size bed also for extra space. I added these sleepers to my registry, but I’m open to any others as well. Does anyone have these or any other recommendations?? Thanks a bunch 🥰
